Panda3D launches with black screen

Scripting Issues

#import statements go here

        #Here, it loads the window the game is displayed on

        # Move the camera to a position high above the screen
        # --that is, offset it along the z-axis.
        self.camera.setPos(0, 0, 32)
        # Tilt the camera down by setting its pitch.
        self.camera.setP(-90)

#runGame will be the first process to run, as it starts the game
runGame = Game()
runGame.run

When I run this code, the screen doesn’t adjust, and there’s just a black screen (of the incorrect resolution).
I get this error message:

I have other Panda3D code that works correctly, so I’m not sure what’s going wrong.

Greetings, and welcome to the forum! :slight_smile:

As to your problem:

Well, your last line doesn’t actually call “run”–it just accesses the method, as though to store a reference to it. (That is, there are no brackets after “runGame.run”.)

That, at least, is the only thing that I see offhand that might be a problem. (But then, I’m not familiar with the “screeninfo” module.)
